TWS earphone and control method thereof

Abstract

The invention discloses a TWS earphone and a control method thereof. The TWS earphone comprises a main earphone used for establishing a first communication link with terminal equipment, and an auxiliary earphone used for establishing a second communication link with the main earphone, wherein the main earphone is used for sending channel information of a first communication link to the auxiliary earphone through a second communication link when it is detected that the first communication link with the terminal equipment is established; the auxiliary earphone is used for forming an initial linkaccording to the channel information of the first communication link, and then adjusting a second clock of the initial link to be synchronous with a first clock according to the first clock of the first communication link so as to establish an interception link for intercepting the terminal equipment; the auxiliary earphone is also used for adjusting a third clock of the second communication linktogether with the main earphone according to the first clock according to the synchronized second clock after the second clock is synchronized with the first clock, and adjusting the third clock of the second communication link to be synchronous with the first clock and the second clock.

Description

Technical field[0001]This application relates to the technical field of portable listening devices, and in particular to a TWS headset and a control method thereof.Background technique[0002]Bluetooth headset refers to the application of Bluetooth technology to hands-free headsets, so that users can avoid annoying wires, and it is a very convenient mobile device receiving device. The traditional Bluetooth headset includes a main headset and a secondary headset. When connected to a mobile device, the signal transmission method is to establish a Bluetooth channel between the mobile device and the primary headset and a Bluetooth channel between the primary headset and the secondary headset, and the mobile device transmits the signal to the primary headset , The main earphone transmits the signal to the auxiliary earphone, and then the main and auxiliary ears broadcast the signal. However, this method has a relatively high energy consumption for the main headset and also requires a high ...

AI Technical Summary

Problems solved by technology

However, when the existing technology is used for signal transmission, it is found that because the mobile device only has a stable link with the main earphone, and the secondary earphone only monitors the link with the mobile device, so the space similar to the distance difference between the mobile device and the main and secondary earphones Interference on the Internet may affect the connection link between the main and auxiliary earphones and the mobile device and the clock of the connection link between the main and auxiliary earphones. Coupled with clock drift, the efficiency of signal reception will decrease after the TWS earphones are used for a long time.
